What is URL Encoding?
URL Encoding is the process of converting string into valid URL format. Valid URL format means that the URL contains only what is termed "alpha | digit | safe | extra | escape" characters. You can read more about the what and the whys of these terms on the World Wide Web Consortium site:
- http://www.w3.org/Addressing/URL/url-spec.html
- http://www.w3.org/International/francois.yergeau.html.
URL encoding is normally performed to convert data passed via html forms, because such data may contain special character, such as "/", ".", "#", and so on, which could either: a) have special meanings; or b) is not a valid character for an URL; or c) could be altered during transfer. For instance, the "#" character needs to be encoded because it has a special meaning of that of an html anchor. The <space> character also needs to be encoded because is not allowed on a valid URL format. Also, some characters, such as "~" might not transport properly across the internet.
What is URL Decoding?
URL Decoding is the reverse of URL Encoding process, as explained above.
